Snagless Pre-Plugs enable you to easily identify different categories of cabling-and department and system applications-via a simple color-coding method.Color-coding makes moving and troubleshooting less of a puzzle, since one application can be easily differentiated from another.Attach Snagless Pre-Plugs before you terminate RJ-45 plugs. They keep the connectors from snagging when you pull the cable through tight spaces. Snagless Pre-Plugs cannot be removed after termination. Each bag includes 50 plugs or boots of the same color.
